1. In a knob or handle, the combination with a peripherally groovedhead, of a headinolosing wire coil seated in the peripheral groove ofthe head, substantially as described.

5 2. In a knob or handle, the combination with a head having aperipheral groove, and sockets in the wall of such groove, of aheadinelosing wire coil seated in such groove and having the ends of thewire bent and inserted 10 in the sockets in the groove-wall,substantially as described.

3. As a new article of manufactnre,a knob comprising a peripherallygrooved head, a head-inclosing wire coil seated in the headgroove, andan attaching-shank, substantially I 5 as described.

In testimony whereof I have hereunto set my hand this 21st day of June,1893.
